==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.04
- Ubuntu 20.10
- Ubuntu 20.04 LTS

Summary:

libwebp could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- libwebp: Lossy compression of digital photographic images.

Details:

It was discovered that libwebp incorrectly handled certain malformed
images. If a user or automated system were tricked into opening a specially
crafted image file, a remote attacker could use this issue to cause libwebp

code.
